Referring by numerals tothe accompanying drawings, and particularly to ythe forni of burner illustrated inFigs. 1 to 5, inclusive, 10rv designates a hollow box-likebody that is 65 preferably formed of cast metal and said body having enlarged end portions 11. The top plate of this hollow `body 10 and its enlarged ends isprovidedwith transversely disposed narrow slotsl 12 which functionas gasemis- 70 sion slots, and these relatively narrow lslots extend vdownwardly a short distance in the side walls of the body 10 and its enlarged ends.

Formed integral with the underside of the body10 and extending from one end thereof 75 to a point shortly past the longitudinal center is a housing 13 that encloses amixing chamber 14V, and the outer end of this housing is eX- tended upwardly and inwardly to form a goose-neck 15 having an open end 16 that oc- 80 cupies a plane above' the upper surface of the body 10.

Formed within the body 10 at the center thereof is a transverse partition 17 having outwardly curved sidefaces 18 and formed 85 in the bottom plate of the body 10 adjacent to the lower end of this partition are apertures 19 that communicate with the mixing chamber 15.

Formed integral with the inner end of the hous-ing 13 and within the mixing chamber 14 immediately below the openings 19 are outwardly curved walls 20 and formed through the side walls of the housing 13 adjacent to the outer ends of these curved walls areopenings 21 that are normally closed by 'removable plugs 22.

When a series of the burner bodies are rcooperatively associated or lwhen gas 1s taken fromythe mixing chamber to an illuminatflected outwardly through the ducts by the curved faces of the wall or partitions 20.

Gas in passing from the mixing chamber 14 through the apertures 19 is deflected outwardly in opposite directions through the ends of the body 10 of the burner by the curved faces 18 of partition 17.

Arranged longitudinally above the body of the burner and supported at one end by a lug 24 that projects upwardly from the burner body, is atubular retort 25, the free end Vof which carries a nozzle 26 in which is formed a relatively small tapered outlet orifice 27 and this nozzle is supported within a hood 28 that occupies a position directly in front of the open end 16 of goose-neck 15.

Secured to the rear end of the retort outside the supporting lug 24 is a fitting y219 to which leads a liquid hydrocarbon supply pipe 30,- and arranged on the outer portion of the fitting 29 is a gland or stufiing box .31. Passing through this gland 31' and through the retort 25 is a rod 32, the forward end of which is tapered to form a Vneedle valve 33, which latter controls the outlet aperture 27 in the nozzle 26. A threaded portion 34 of the rod 32 engages a correspondingly threaded portion of the fitting 29 andthe outer end of rod 32 carries a handle 35. Y

Retort 25 occupies a slightly inclined position with its rear end llowermost and thus any liquidhydrocarbon that may accumulate within the retort will, by gravity, pass to the from the orifice 27 by manipulation of rodV 32 the gas will discharge from the nozzle of -the retort into goose-neck l5 and simultaneously with such discharge a certain amount of air will be drawn into the goose-neck and pass with the-gas into the mixing chamber 14 and after passing therethrough this mixture of gas and air will pass .upwardly through the openings 19 and by the curved surfaces 18 said mixture will 'be caused to pass outwardly through the chambers within the burner body and said mixture will then pass through the narrow slots 12 and combustion of the mixturewill take place ontop of the burner body.

Inasmuch as the retort is positioned directly over .the burner body said retort will be maintained in a highly heated condition so as to vaporize the liquid hydrocarbon that yenters the retort through tube 30.

In the modied construction illustrated in Fig. 6, the burner body is constructed separately from the housingV 1.3 and the two parts` gooseneck to be utilized with different forms of burner bodies.

In the modied construction illustrated in Figs. 7 and 8 a substantially circular burner body 37 provided with-gas emission slots 38 in its upper plate is provided with a diametrically arranged partition 39, thereby forming two separate chambers 40, and formed on one side of thev body 37 are two goose-neck members 41, one for each chamber 40.

Over-lying the burner body 37 is a pair of retorts 42, the free ends of which are arranged to discharge into the open ends of the goose-neck members and the rear ends of the retortsare connected by a fitting 43, and connected to the latter is a liquid hydrocarbon` supply pipe 44.

vThe fitting 43 is provided with glands 45 through which pass stems 46 of the valves that control the outlet openings in the nozzles carried by the forward ends of the retorts In this formof burner the two retorts may be utilized independentlyl or Where both'retorts are vbeing used lat the same time and the outlet orifice from either retort becomes closed by carbon accumulations the gas generated in theV closed retort will pass to and u throughthe other retort so that the burner remains in operation even though one of the retorts istemporarily out of service.

In kthe modified construction illustrated in Figs. 9 and 10a goose-'neck47 is formed integral with and extends downwardly and outwardly from one side of the bodyr 48y ofthe burner and formed on the interior of the burner body immediately in front of the opening into the goose-neck is a horizontally disposed V-shaped member 49 that functions as a deector to cause the mixture of gas and air that enters the body from the goose-neck to be deflected laterally :in both directions and thereby discharge evenly through the out- Y let slots in the top of the burner body.

In the lower portion of the goose-neck 47 Y f to the chamber within the burnerbody 55.

i above the burner body 51 is a retort 53 and the nozzle thereof is arranged to discharge into the open end of a horizontally disposed goose-neck 54 that is formed integrally with 1 and projects laterally from the corresponding end ot the burner body 50. In this construction the burner bodies and 51 occupy thev same horizontal plane and a relatively large flame area is produced.

In the modified construction illustrated in 1 Figs. 13 and 14 a burner body 55 has formed integrally'with its top plate a centrally arranged longitudinally disposed duct 56 and formed in the wall above saidfduct is a series of gaseous emission slots 57. One end of the duct 56 terminates in a goose-neck 58 that is arranged immediately below a larger gooseneck 59 that extends outwardly, upwardly and inwardly from the burner body 55.

producing! a maximum degree ot heat, the

retort 63 has its nozzle G2 positioned in the uppermost one of the apertures 61 so as to discharge into the open endot the goose-neck 59 and thus gas and airwill be delivered When it is desired to produce only a relatively small amount ot heat the retort is adjusted so that its nozzle is positioned in the lower'one of the apertures 16 and when so positioned ga'sand Iair will discharge into the goose-neck 58 that leads to duct 56 and the flames of theburning gas issuing from the slots 57 will act as pilot lights to light the burner when the same is utilized for producing a maximum degree of heat, and at i' the same time said pilot lightswill develop suflicient heat within the pilot to vaporize the liquid hydrocarbon that is delivered thereto,

vthus producing sutcient gas to maintain the pilot lights.

The burners embodying the principles of my invention may be used singly or in com- Vbination and said burners may be made in various sizes Mid shapes depending upon the purpose for which they are intended.

A further desirable and economical feature of my invention is the construction and arrangement whereby a highly intlainmable gas is generated from gasoline, distillate or llike liquid hydrocarbons and which gas may y Y vbe taken to points remote from the generator and utilized for illuminating or heating purposes. c Y

Thus it will be` seen that I have provided a combined gas generator,burner and illuminating appliance that is relatively simple in construction, inexpensive otl manufacture and Vvery ei'lective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form-and construction ot the various parts et my improved combined gas genera tor, burner and illuminating appliance may be made and substituted orfthose herein shown and described without departing from the spirit ot' my invention, the. scope of which is set forth in the appended claims.
